6. From Structure to Function with Binding Free Energy Calculations for Codon Reading, Riboswitches and Lectins
Sammanfattning : Molecular association is part of many important processes in living cells. Computational methods for calculating binding free energies allows for a quantitative examination of biomolecular structures and hypotheses drawn from biochemical experiments. LÄS MER
7. Computational Studies of Protein Synthesis on the Ribosome and Ligand Binding to Riboswitches
Sammanfattning : The ribosome is a macromolecular machine that produces proteins in all kingdoms of life. The proteins, in turn, control the biochemical processes within the cell. It is thus of extreme importance that the machine that makes the proteins works with high precision. LÄS MER
8. Studies of platelet signalling and endothelial cell responses using unique synthetic drugs
Sammanfattning : Haemostasis is a complex and tightly regulated process which protects us from bleeding. Platelets are essential for maintained haemostasis. Under normal conditions platelets are calmed by antithrombotic substances release by the endothelium. During vascular injury, the platelets will activate and form a haemostatic plug to prevent bleeding. LÄS MER
9. Excitation and Excited State Properties of Heterocyclic Chromophores. Indole and Purine Derivatives of Biological Significance
Sammanfattning : Proteins and nucleic acids absorb light in the near-UV due to the presence of aromatic heterocyclic chromophores. In this work linear dichroism (LD) in combination with fluorescence polarization anisotropy (FPA) and magnetic circular dichroism (MCD) is used to investigate electronic excitations and excited states of indole derivatives, purine derivatives, the wye base, 2-phenylindole and 4',6-diamidino-2-phenylindole (DAPI).

10. Myocardial energy metabolism in ischemic preconditioning, role of adenosine catabolism
Sammanfattning : Brief episodes of ischemia and reperfusion render the myocardium more resistant to necrosis from a subsequent, otherwise lethal ischemic insult. This phenomenon is called ischemic preconditioning(IP). LÄS MER
